Abstract

An actuation system for assisting the operation of a natural heart is disclosed. The actuation system includes a framework (50) for interfacing with the natural heart and an actuator mechanism that can be coupled to the framework. The framework includes internal framework (52) and external framework (70) elements. The actuator mechanism is operable for deforming at least one framework element (52, 70) for varying the shape of the heart. The framework includes a set of interconnected, passive, intracardiac and extracardiac elements (52, 70) and their interconnections that deform, bend and/or twist in response to movements induced by the actuation system. Some or all of these elements, and the connections between them, are specifically intended to be flexible, in that they may be bent or twisted by means of motion induced by an associated mechanical actuation system (76).
